The discovery and application of immune checkpoint inhibitors (ICI) have significantly promoted cancer treatment. However, the response rate is still low in gastrointestinal (GI) cancers. To explore novel adjuvant treatment options, we performed fecal microbiota transplantation (FMT) of healthy donors on 10 GI cancer patients with resistance to anti-PD-(L) 1 treatment. The combination of FMT and anti-PD1 treatment was well tolerated and no serious adverse reaction was observed. Two out of 10 patients restored clinical responsiveness to anti-PD1 after FMT. Clinical benefits were shown to be associated with better colonization of co-occurred immunogenic microbes from donors, alongside activated immune status reflected by the peripheral immune cell population. Moreover, we identified microbial signatures of ICI responsiveness and validated in an independent cohort. Our study demonstrates the feasibility of FMT as a potential adjuvant therapy for ICI irresponsive GI cancer patients and laid a foundation for LBP / consortia development to enhance ICI efficacy.
